Problems solved by technology

[0003] At present, the wireless resources required by the terminal device to transmit data on the secondary link can work based on the network-side device scheduling mode, but the existing terminal device reports a scheduling request (SR, Scheduling Request) and a buffer status report (BSR, Buffer Status Report) The way to apply for resources, in the case of uplink resource conflicts or insufficient uplink resources, will fail to meet the transmission requirements of services carried on the secondary link because the smooth reporting of SR and BSR cannot be guaranteed

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] In related technologies, the Long Term Evolution (LTE, Long Term Evolution) / Enhanced Long Term Evolution (LTE-A, Long Term Evolution advanced) communication system supports a secondary link (SL, Side Link), which can be used by the user end ( UE, User Equipment) can directly perform data transmission without passing through the network side equipment.

[0031] Such as figure 1 As shown, the network side equipment is used as a base station for i...

Abstract

The invention discloses an uplink transmission method, which is applied to a terminal device. The method includes: in the case that the uplink resource used to transmit a target scheduling request SR conflicts with other resources, according to the scheduling request transmission rule corresponding to the target quality of service requirement, determine Whether to perform the operation of transmitting the target SR on the uplink resource, the target SR is the SR triggered by the target buffer status report BSR, and the target BSR is the BSR triggered by the data to be transmitted on the secondary link. In the embodiment of the present invention, when resource scheduling conflicts, according to the pre-established scheduling request transmission rules corresponding to the target quality of service requirements, the execution status of the scheduling request uplink transmission corresponding to the data to be transmitted on the secondary link is determined to effectively It can effectively solve the problem of resource scheduling conflicts, so as to meet the transmission requirements of different types of services.

Description

technical field [0001] The present invention relates to the communication field, in particular to an uplink transmission method and terminal equipment. Background technique [0002] In the new air interface (NR, New Radio) of the fifth generation (5G) mobile communication system, the new air interface secondary link (NRSL, New Radio Sidelink) supports advanced Internet of Vehicles with strict transmission requirements in terms of low latency and high reliability. (V2X, Vehicle To Everything) business. [0003] At present, the wireless resources required by the terminal device to transmit data on the secondary link can work based on the network-side device scheduling mode, but the existing terminal device reports a scheduling request (SR, Scheduling Request) and a buffer status report (BSR, Buffer Status Report) The way to apply for resources, in the case of uplink resource conflicts or insufficient uplink resources, cannot meet the transmission requirements of services carr...
